According to James E. Post, common is a shared resource, such as land, air, or water that a group of people uses collectively. In the article title, Water: Critical shortages ahead?-water is a resource shared globally and its consumption has raised six fold between 1900 and 1995-more than double the rate of population growth. According to a 1997 United Nations assessment of freshwater resources found that one third of the world's population lives in countries experiencing moderate to high water stress. Moderate to high stress translates to consumption levels that exceed 20 percent of available supply. The article, points out that, "much of the projected increase in water demand will occur in developing countries, where population growth, industrial and agricultural expansion will be greatest". As a result, the World Resources Institute states that, "agriculture already accounts for about 70 percent of water consumption worldwide and the United Nations projects a 50 to 100 percent increase in irrigation water by 2025". The article points out that if water demand continues to grow and agriculture continues to dominate the water usage worldwide, water supplies will shrink and groundwater reserves will began to be depleted faster than they can be replenished by precipitation. This will have a negative impact throughout the globe as countries and societies will began to experience water scarcity-especially the low income nations. This will drive the industrialize nations to regulate the consumption of water as well as raise the price of water to discourage waste and abusive. This will greatly affect the low-income nations as they lack the financial and technological capabilities to keep up with the raise demands of water. According to the World Resources institute, "this situation has already caused serious water shortages to develop in some regions, shortchanging human water needs and damaging aquatic ecosystems".

...-Introduction
The term globalization is commonly used now, and it doesn’t only bring benefits to the world but also many problems. The purpose of this paper is to define and discuss the cause and effect of four global issues: overpopulation, water scarcity, global warming, and marine pollutions. The increasing number of population will cause serious problems in the future and I really want to know why was the population unstoppably rising and how humans will do to prevent overpopulation. So overpopulation is an issue that I want to know and find some solutions about. Global warming is affecting everything on the earth now; species living in the Arctic are dying, including one of my favorite animals, polar bears. So I want to learn about global warming and find ways to save polar bears. There are many people suffering by water scarcity; they can’t drink or use clean water, and some of them died because of thirst. I want to help them to have the same lives as we do, so I chose to research on water scarcity. Last but not the least, the leakage of oil in the ocean is happening more frequently, this has affected the lives of marine animals a lot. It will cause bigger problem if we can’t solve it, so I would like to find some solutions about it.

Global Warming
Global warming is something that I believe needs to be improved on. Climate change is hitting us hard. Global warming is severely effective to us and how we live. Also, it is something that more than one person can take action to help improve.
Climate change is happening now. Over the past century, the actions that humans have caused the climate to change over the years. The gases such as carbon dioxide is being released in the air acting as a blanket trapping the energy and allows it to become warmer. Our lives are connected to the climate. A warming climate will bring changes that can affect our water supplies, agriculture, power, and transportation systems, the natural environment, and even our own health and safety. Carbon dioxide can remain in the atmosphere for nearly a century. This means the earth will continue to become warmer and warmer by the century. Carbon dioxide (CO2) and other greenhouse gases always have been present in the atmosphere, keeping the earth hospitable to life by trapping heat. Yet, since the industrial revolution, emissions of these gases from human activity have accumulated steadily, trapping more heat and giving out the natural greenhouse effect. As a result, global average temperatures have risen both on land and in the oceans, with huge impacts already occurring that increasingly severe changes in the future....

...Global Warming
As we know, global warming is becoming a global issue. It alarms the whole world to protect the destroyed environment. Global warming is a "natural phenomenon". In general, we know that the origin of global warming is the emission of carbon dioxide. It was verified that the relationship between carbon dioxide and temperature: when there is more carbon dioxide the temperature gets warmer. This topic should be discussed under current situation to advocate people concerning with this severe environmental issue. Meanwhile, people should consider how to reduce the emission of carbon dioxide and take some actions to stop global warming.
What is global warming? Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation. According to the 2007 Fourth Assessment Report by the Intergovernmental Panel on Climate Change, global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 20th century. In nearly 100 years, the average global temperature goes through four fluctuations: cold, warm, cold again, and warm again. After 1980s, the temperature was ascending obviously.
We can see the changes through an experiment. Have students mix 4 tsp. of salt into an 8-oz. glass of tap water from the fridge and add it...

...Global Warming
Recently, there have been many problems with hurricanes, heat waves, and floods. What could perchance be causing all of this? One of the main reasons there has been so many natural disasters and complications is global warming. Global warming is the rising average temperature of Earth's atmosphere and oceans due to the greenhouse effect. The greenhouse effect consumes greenhouse gases in the earth’s atmosphere which causes the heating of the earth and very high temperatures and causes Arctic ice to melt. Mainly, online sources were used. Due to a lot of researching I've done, I came to a conclusion and found out that the main solution to reducing global warming is to reduce the amount of greenhouse gases released in the air but first, let me explain what global warming is, the history of global warming, what population is global warming affecting, and what is being done to prevent global warming.
The effects of global warming create a growing danger for the ecosystem we live in by damaging animals, coastlines, habitats, and much more. Global warming is the heating of the earth caused by the “greenhouse effect”. The greenhouse effect is the warming that happens when certain gases in the earth’s atmosphere trap heat. Some of these gases occur in nature. For example, water vapor, carbon-dioxide, and methane. Other gases...

Global warming the biggest threat in 21st century
Introduction
The term global warming has been common in the fields of whether and climate. The term does not posses the literal meaning as such but simply implies change in climate. The change in climate is attributed to overall rise in average temperatures of the universe. This poses a great threat to mankind (Korgen, 2007). The dangers attributed to global warming include health issues, scarcity of some vital natural resources, increase in temperatures of the natural water bodies and general fall back of economy.
According to the view of professionals and researchers in the medical field, global warming is one of the top agendas that need immediate attention for its predicted threat to the living standards of human beings. Some of the threats linking to health include scarcity of water, poverty and eclipsing infectious diseases. These phenomena will be felt in countries that are still developing and will further join existing food shortage. These effects will not only affect the present generations but also generations to come (Yan & Crookes, 2007).
Having a planet that is warmer will lead to flooding of coastal cities causing mass migrations especially for settlers in the coastal regions. Fights over resources like food and water will be among the top stories in this century. The resources will be inadequate to meet the needs of...

...Controversy over Global Warming
One of the largest argued topics in our world today is over global warming. People argue that is real, and others argue that it is fake. The effects of global warming create a growing danger for the ecosystem we live in by damaging glaciers and weather patterns. Humans contribute to global warming yet non-believers will think otherwise. Global warming is the greatest challenge facing our planet. According to the IPCC (Intergovernmental Panel of Climate Change) most of the case for global warming is a process that occurs when rays from the sun pass through the atmosphere warming the surface of the planet. In short, global warming represents a fundamental threat to all living things on earth.
Global temperature has risen significantly during the past century. The scientific view is that most of the temperature increases since mid-20th century has been caused by increases in the greenhouse gas concentrations, which are produced by everyday human activity. Most scientists agree that if people stop burning fossil fuels the greenhouse gases already e mitted will warm the planet two degrees by the end of the century. “The fact is, we are not making a lot of progress in reducing emissions”, Richard Moss. (nbc.news) As a result, the world is getting increasingly warmer and warmer each year. The years of 1983, 1987, 1988 and...

What is Global Warming and how is it formed?
Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as co2 from burning fossil fuels or from deforestation which trap heat that would otherwise escape from Earth. Global warming is a problem of too much CO2 in the atmosphere which is like a blanket trapping heat and warming the...

a) What is the Global Warming?
Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die.
Any things cause global warming. One thing that cau ses global war ming is electrical pollution.
We use these sources of energy much more than the sources that give off less pollution. Petroleum, one of the sources of energy, is used a lot. It is used for transportation, making electricity, and making many other things.
